Hello there. I really like the M+. I went to it from the original Optimus M, and am very happy with the phone. We got root, and CWM pretty early on; as well as an overclock kernel (unfortunately, it breaks wifi though, so be aware of that if you use or rely on wifi). I have rooted and applied the CWM recovery, but haven't flashed the overclock kernel. As far as ROM development, it seems to have ground to a halt. However, I'm still pretty happy with the stock ROM. It's pretty customizable as it is; I have applied holo launcher, so have an ICS look to my phone. A lot of the bloat ware is removable even before root, so that will help clear up space; not that this phone is at a loss for space. It has a decent amount; I currently have used 456MB out of the 1GB of system memory, and 1.3GB of the 1.89GB internal memory. I have a little over 50 apps that I've installed. Compared to the 200MB of internal memory that my OM had, this is enormous. I had to use the A2SD from DarkTremor in order to get enough memory so that I could run apps on my original OM.

This is a pretty snappy phone as well. The only time I seem to have any slowness, is (occasionally) when I try to turn on wifi. It seems to really bog down and lock up. I don't know if it is actually locked up, or just bogging down so much that it seems like it's locked up. This doesn't happen all the time, and I've taken to leaving wifi on most of the time anyway.

Overall, if you don't need cutting/bleeding edge devices, this is a good phone to have.

Welcome to the forums, also.
